The last step is to monitor and evaluate your software after the deployment. Monitoring can help you track and measure the performance, availability, and reliability of your software, as well as identify and address any problems or incidents. You can use tools and metrics, such as logs, dashboards, alerts, and key performance indicators (KPIs), to monitor your software. Evaluating can help you assess the outcomes, impacts, and benefits of your software, as well as identify and implement any improvements or enhancements. You can use tools and methods, such as feedback, surveys, analytics, and reviews, to evaluate your software.
